摘要
在铁矿粉资源劣质化以及烧结设备、操作工艺参数发生较大变化的背景下,采用烧结杯试验方法对首钢京唐公司烧结用主流铁矿粉进行了单种矿烧结试验研究。结果表明:京唐各主流矿粉单烧时,烧结指标各有差异,需搭配使用以达到优势互补。就铁矿粉类型而言,京唐赤铁矿类型铁矿粉烧结指标优于褐铁矿。赤铁矿中巴卡粉优势较为突出,而褐铁矿类型铁矿粉中杨地粉A具有较为明显的优势。就巴西粉而言,巴卡优于巴烧;对澳粉来说,纽曼优于PB粉;杨地粉A优于杨地粉B。
Based on the background： quality of iron ore powder being more and more worse,great changes having taken place in sintering equipments and operation process parameters,the single- kind- ore sintering test and research are conducted for major iron ore powder with sintering pot in Jingtong. It is showed from the result that when sintering with single kind of major powders,the sinter indexes are different for each kind of powders,the powders must be mixed to use to get their advantages complemented each other. As to type of iron ore powder,the indexes of hematite type is better than that of limonite; that of Brazil Vale Carajas powder is the best among hematite type; the BHP Yandi JV powder A has a obvious superiority in limonite type. As to Brazil powders,Carajas is better than Brazil sintering; as to Australian powder,BHPB is better than Rio Tinto,the BHP Yandi JV powder A is better than BHP Yandi JV powder B.
